The affordable Parallel alternative
Serpex is a web search API for AI agents that returns search results and the full page content behind them as LLM-ready markdown in a single request. Parallel is a web search and deep-research API for agents, priced per request. Parallel lists $1.00 – $5.00 per 1,000 searches; Serpex lists $0.50 – $0.80 — about 2× lower.

Where Serpex is different
- Cheaper at the low end, and predictable — one price per search, not a processor ladder
- Full page markdown, not excerpts, when you ask for content
Where Parallel is the better choice
- The Task API handles multi-step deep research as a managed job — we do not offer an equivalent
- Processor tiers let you dial research depth up dramatically for one-off hard questions
- Among the closest competitors to us on price in this list
Pick Parallel if you need managed deep research rather than search primitives — their Task API does a job we deliberately do not.
What the Serpex request looks like
One call returns the results and the page content behind them. There is no second request to orchestrate.

Is Serpex cheaper than Parallel?
Yes. Parallel lists $1.00 – $5.00 per 1,000 search requests. Serpex lists $0.50 – $0.80 per 1,000 — roughly 2× lower at list price. Verified against their public pricing page on 2026-10-01.
What is the main difference between Serpex and Parallel?
Parallel is a web search and deep-research API for agents, priced per request. Serpex returns search results and the full page content behind them as LLM-ready markdown in a single API call, which is the difference that matters for most retrieval pipelines.
When should I use Parallel instead of Serpex?
You need managed deep research rather than search primitives — their Task API does a job we deliberately do not.
Can I get both search results and page content in one request?
With Serpex, yes — set include_content on a normal search call and each result comes back with the page converted to markdown. That costs $3.00 – $4.80 per 1,000 requests for 10 results with content, against roughly $11 to $15 with Extract on all 10 results (excerpts alone come with the $1 to $5 search) for the equivalent on Parallel.
